EV Charging
Tesla Wall Connector Installation
Wall Connector mounted, wired, and load-shared where needed.
What the job involves
Wall Connector mounted, wired, and load-shared where needed. Most of what goes wrong with this is not the device itself. It is the connection behind it, the circuit feeding it, or a load that outgrew what was there.
There is no mystery to it. It goes in this order. We see this go wrong most often when someone extended an existing circuit instead of running a new one.
How we handle it
- Load calculation before any equipment is ordered
- Continuous load sizing at 125 percent
- Mounted where the cable reaches without strain
- Tested at full draw before sign off
Doing this in the White Mountains
Houses up here run on long service drops and a lot of them were wired for a cabin load, not a full-time household.
Elevation, weather, and the age of the housing stock all change how this work goes here compared with a valley city. Equipment ages faster in this sun, monsoon surge is a real load on the system, and a lot of these houses were built as seasonal property and are now carrying full-time demand.
We do not upsell a panel when the problem is a loose neutral, and we do not patch a service that needs replacing.
Choosing the amperage honestly
Bigger is not automatically better. A 48 amp charger on a house that can only support it by upgrading the service is often worse value than a 32 amp charger that fits the existing panel and still adds well over a hundred miles overnight.
The useful question is not how fast the charger can go, it is how many miles you drive in a day and how many hours the car sits at home. For almost every household the answer makes 32 or 40 amps entirely sufficient.
Where higher amperage genuinely earns its cost is a two-EV household, a long daily commute, or a vehicle with a very large battery that you regularly run low.
Continuous load, and why it changes the wiring
A charger is legally a continuous load, which means it is expected to run at its full rating for three hours or more. The code responds by requiring the circuit to be sized at 125 percent of that rating. A 40 amp charger therefore wants a 50 amp circuit, and that is not a safety margin somebody invented. It is the difference between a conductor running warm and a conductor running hot for six hours every night.
This is also why a charger cannot simply share the dryer circuit, an arrangement that gets suggested surprisingly often. The dryer runs for 45 minutes. The charger runs all night. The wiring behaves completely differently under those two loads.
It is the most common place we see a well-meaning DIY install go wrong: correct amperage on paper, wrong assumption about duty cycle.
What commissioning a charger actually involves
Energizing a charger is not the same as proving it. We put the unit into its full rated draw with the vehicle connected, measure the actual current on each leg, and check the voltage under that load rather than at rest. A connection that reads fine with nothing flowing can collapse when forty amps arrives.
Then we let it run. A charger that faults out at minute forty has a different problem than one that never starts, and neither shows up in a five minute check. We confirm the ground fault protection actually trips on test and resets, and we verify the unit’s own amperage setting matches the breaker and the conductor rather than a factory default somebody forgot to change.
Last comes the boring part: labeling the breaker, telling you where the disconnect is, and showing you what a normal indicator sequence looks like so an abnormal one is obvious.
What you get
- LicensedC-11 #192532 and R-11 #192533

Conduit in the garage, and leaving room for later
Cable stapled across an unfinished garage wall is exposed to whatever a garage does to things: ladders, bicycles, a bumper, a shelf bracket. Physical protection is required where damage is likely, and in a garage it is likely. Conduit solves that, and it also solves the future.
Running a size larger than today’s circuit needs costs very little while the trench or the wall is open, and it means the next charger, or a second one, or a shop subpanel, is a pull rather than a demolition. Conduit is the cheapest thing on the job and the only thing that buys you options.
For a detached garage the same logic applies with more force, because the trench is most of the cost. Whatever goes in that ditch should be what you want there in fifteen years.
Questions we get
Level 1 or Level 2?
Level 1 is a standard outlet and adds a few miles an hour. Level 2 is 240 volt and fills overnight. For anyone driving daily, Level 2 is the real answer.
Hardwired or plug in?
Hardwired is cleaner and required outdoors in some cases. A receptacle lets you take the unit with you. Both are correct when done right.
Do you work with every brand?
Tesla, Ford, Chevrolet, Rivian, ChargePoint, Wallbox, and the rest. The circuit behind them is the same work; the mounting and commissioning differ.
Are you licensed?
Yes. We hold a C-11 commercial license, number 192532, and an R-11 residential license, number 192533. Both are current and we are insured.
How long have you been doing this?
The company is two years old. The owner has eight years in the trade before that, which is where the experience behind the work comes from.
Towns we cover
Based in Pinetop-Lakeside, covering about forty miles out across Navajo County and the western side of Apache County.
- Show LowOur second base. Panel work and service upgrades on the newer builds off Deuce of Clubs.
- Pinetop-LakesideHome ground. Cabin rewires, fixture work at cathedral-ceiling height, and same-week calls.
- SnowflakeLonger runs out to property on acreage, where the well pump and the house share one panel.
- TaylorOlder service entrances that predate the current code, and the corrections that go with them.
- Heber-OvergaardHeavy second-home territory. Freeze-season calls on places that sat empty since fall.
- LindenBetween Show Low and Pinetop. Remodel wiring and additions on established lots.
- GreerHighest elevation we cover. Generator and backup work for a road that closes in weather.
- ConchoWide-open lots on the Apache County side, often with a long feed from the meter to the house.
- OvergaardPonderosa country. Fixture and circuit work in cabins built across four decades.
- LakesideOlder lakefront cabins where the original wiring was never meant for today’s load.
- PinetopThe cabin core. Small jobs, one outlet or one switch, are most of what we do here.
